A delayed cycle can look broken for an hour. A fork sticking through the lower rack can stop the door from latching by a distance too small to notice from standing height.
Controls and water supply are the owner checks. A latch replacement or terminal inspection means removing panels and leaves this guide.
Before you touch it
Checks that can change the diagnosis
- Confirm the water valve is open.
- Check Control Lock, Sleep and Delay Start.
- Look for a rack or utensil blocking the door.
- Listen for the latch click.
- Check the dedicated breaker once.
Try this in order
The safe troubleshooting sequence
Close the door again
Remove anything protruding from a rack and close the door firmly without slamming it.
Wake and unlock the controls
Use Start or open and close the door, then disable Control Lock as the manual describes.
Cancel the delay
Clear Delay Wash and any old cycle using Cancel or Drain.
Open the water valve
Confirm the under-sink dishwasher valve is fully open and dry.
Reset power once
Turn the dishwasher breaker off for 30 to 60 seconds, then restore it.
Try one normal cycle
Stop if the breaker trips, a burning smell appears or the machine leaks.
How you know the simple fix worked
The door should latch and the machine should begin filling during a normal cycle. A silent machine after the reset needs service.
Technician territory
Stop the job when you see any of these
- Repeated breaker trips
- Burning smell or scorched wiring
- A physically broken latch
- Any need to remove the toe panel or test wiring
The claim can change the repair decision
Maintenance, a warrantyWritten warrantyA written promise supplied with the appliance sale.

Sales pages often call it an extended warranty. are different things.
An active lock or delayed start is not a failed part. A broken latch or control may be a covered repair, so photograph the panel state before resetting it. Federal warranty protections do not make every DIY mistake covered, and a paid service contract may require authorization before a part is replaced.
Common questions
The short answers
How long should I leave the dishwasher breaker off?
Use the owner's manual. Many makers direct a 30 to 60 second reset, performed once.
Can I replace the door latch myself?
This guide stops before panel removal and wiring. A damaged latch should be handled as a service repair unless the exact manual says otherwise.
